中文摘要： 信息技术的发展对高速、廉价、微型化的光子学器件提出了新的要求。如何设计与制备纳米光子学器件单元，实现在可调谐激光光源、光通信、光显示等领域中应用，是一个具有挑战性的课题。有机光功能材料的优异加工性能、发光效率和光学可控性等优势吸引了广泛的关注。在本项目中，我们拟在有机分子设计、低维光功能材料制备的基础上，挑选并优化合适的纳米结构微腔以及构筑分布式布拉格反射镜或光子晶体微腔，通过单个或者多重微腔结构实现对光定向传导和发射的可控光流操纵。重点研究基于微腔结构对光子的限域作用导致的诸如激子极化基元产生和传导、极大曲率条件下光波导和低阈值受激发射等，初步揭示低维材料的组成、形貌结构与光学微腔之间的关系，微腔光学调控内在调控机制，尝试将低维微腔有机材料器件化和应用化，对低维有机纳米光子学器件的研制起到理论和实验的指导意义。

英文摘要： The development of information technology required more advanced high-speed, low-cost and miniaturized photonic devices. A critical challenge is the design and fabrication of nanophotonic device elements and the application in the field of tunable laser sources, optical communications, and displays. Organic optical functional materials are paid more attentions due to their processability, high luminous efficiency and optical tunability. In this project, we will optimize nanostructural microcavities and construct distributed Bragg reflectors (DBR) or photonic crystal (PC) microcavities based on the organic molecular design and the fabrication of low-dimensional optical functional materials. The regulation of light directional waveguide and emission by means of single or multiple microcavities is investigated. We will highlight photon confinement in the microcavity structures and derivative exciton-polariton (EP), optical waveguide, low-threshold stimulated emission, and so on. We will attempt to disclose the relationship of the constitutions, morphologies and optical microcavites in the low-dimensional materials and interior mechanism of optical modulation. We will attempt to make them into device applications and provide a theoretical and experimental guidance for low-dimensional organic nanophotonic device.
